Hot Spring Spas 1500w circulation heater replacement kit for replacement of current models 2003+ with pressure switch cord

Has 2 x temperature sensor locations - hi limit and control. 
3/4" barbs for tubing connection 

*Its extremely important that you ensure water has flooded the heater and is flowing through the plumbing (primed) after installation and after every drain/refill. 
Failure of the heater due to 'Dry Running' will likely result if the heater has not properly primed. 
This is not a manufacturing defect and therefore not a warranty covered failure. 

This heater kit is for replacement of heater models with a second small wire with internal pressure switch, and includes the following: 
Inline flow switch and connection tube / clamps

These extra parts are not needed for Hot Spring Spas with heaters that have no separate pressure switch wire, however if fitted to a IQ2020 controller, can be used for additional heater protection by connecting to P34 terminals.
